Trixie and Prince Charming by Rixizu
https://www.fimfiction.net/
Princess Luna couldn't be more proud of her newest student Trixie. The filly was bold, smart, and daring to a fault. Unfortunately, over the last couple of months, Trixie still hadn't been able to make any friends in Canterlot at all and had adapted poorly to life in the castle and the Night Court. Trixie was an oddity to the upper echelons of society, a poor filly with no money or title to her name at all and a notorious troublemaker. Determined to do everything in her power to fix this, Luna sets Trixie on a playdate with one of the foals of the Night Court nobles to get her student the friendship and love she needs. And Luna has the perfect candidate, a lovely little colt Trixie's age named Prince Blueblood.

Sad/Dark
Descent into Hell by DemonBrightSpirit
https://www.fimfiction.net/
Ponyville. That is where my fall from grace began. Twilight Sparkle and her insurmountable talent exposed me for the charlatan I was. After that inauspicious day, my shows were no longer a thunderous triumph of magic and trickery. They were a blighted sideshow—a mockery of the splendor they had once been.
In my desperation to retain the life I once held, I stooped lower and lower. I finally hit rock bottom on a remote rock farm. There, I assumed the life of some ordinary, mundane pony, hammering away at boulders until nothing but pebbles remained. It was beneath me, humiliating and degrading. The days dragged on, but my dignity fell no further. It was the bottom, the very bottom, where nothing could fall any lower.
If I had it to do over again, I would have clung to that humble bottom. I would have held on and never let go.
I made the worst mistake imaginable. In my desperate bid to claw my way back up to the graces I once knew, I put my faith in dark magic. While I may have found the bottom on that rock farm, that accursed amulet drug me even deeper, pulling me into the abyss of hell.
